Since you are in the UK, I would guess you'd have better luck over there tracking down Slazenger gear than over here, but the X1 used the same kit as the old black and white Pro Braided or the Henman Trinity Braided versions. If you can find those, you should be good to go.

I believe there were some posts many years back when the black/white version was around that the Wilson Pro Staff 6.1 grommets and bumperguard fit the Pro Braided. If you can find those anywhere, it may be worth a shot.
